T0 all 'whom t may concern f Be it known that I, FRANKLIN' CHATFIELD, of Minneapolis, Hennepin county, Minnesota, have invented certain new and useful Improvements in Fabric-Guides for Stitching-Machines, of which the following is a specification.

The object of my invention is to provide means for easily and quickly regulating the distance of the line of stitches fromthe edge of the fabric. The invention consists generally in various constructions and combinations, all as hereinafter described and particularly pointed outv in the claims.

In the accompanying drawings forming part of this specification, Figure 1 is a view, partially insection, illustratingthe application of ,my fabric guide to a stitching machine, Fig. 2 is a side view, also partially in section, showing the position of the fabric guide with respect tothe presser foot and the mechanism for operating the guide, Fig. 8 is a plan view,` showing the manner of mounting the kfabric guide on the machine, Fig. 4 is a detail sectional view .of the means for adjusting the fabric guide, Fig. 5 is a detail sectional view showing 'the means for adjusting the guide toward and from the presser' foot, Fig..6vis a sectional view on the line azi-m of Fig.y 5.

In the drawing, 2 represents the frame of the machine, 'and' 3 the Work table. 4 is a needle, 5 the presser foot, and 6 thereciproeating hook which cooperates withk the needle to form the stitch. These parts are all in use with the ordinary shell stitching machine. A

7 is a plate secured to the machine frame and 8 is a second plate between which and the plate 7 a guide-way is formed. In this guide-way is a slide 10. A pin 11 is mounted;

in the plate 7 and projects into an' opening 12 in the slide 10 in which a spring '13'is' arranged. The compression of this spring normally tends to hold the slide in its retracted position against the pin 11, shown in Fig. 4. A fabric guide 14 is mounted on the slide 10 and provided with a rearwardly projecting end 15 having a vertical slot 16 that is adapted to receive the laterally projecting pin 17 on the presser foot. This pin bridges the gap between the presser foot and the fabric guide and prevents the fabric and justed`toward or from the presser foot against thecompression of this spring yuntil thev desired bigh't of the stitches is obtained.

kVarious devicesmay be employed for operating the fabric guide, but I prefer to pro vide the mechanism which I will now describe in detail. The plate 7 carries an outwardly projecting stud 18 supporting a sleeve 19 that is slidable on said stud and also adapted to rotate thereon and provided at its innerend with a seat 20 between which and a screw head 21 on the stud 18 a coiled spring 22 is arranged. vThe compression of this spring is evidently increased by moving the sleeve outwardly on its supporting stud and decreased when the sleeve is pushed inwardly. A plate 23 is mounted on the inner end of vsaid sleeve and hasa. split lower portion 'provided with a clampscrew 24 forfsecuring the plate 28 on said sleeve. The upper portion ofk said plate has a transverse slot 25 to receive a pin 26 that is carried by the slide 10 and projects outwardly through a slot 27 in the plate 8. When, therefore, pressure "is applied to the pin 26 the slide 10 will be pushed .outwardly to move the fabric" f guide toward the presser foot to change the distance of the `line of stitches from the edge of the fabric. M

For the purpose of moving the pin 26 I in a socket 1n the upper portion of the plate `23 and having one end contacting with the pin 26 and its opposite end engaged by a `provide a slidingl pin 28 movable lengthwise "d lever 29 that is fulcrumed at 80 and has a limited rocking movement. I prefer to provide a set screw forming a fulcrum for said place. The outer end of the sleeve 19 has a` finger grip 32 and upon said sleeve a collar 33 is mounted, having a finger grip 34. y A

` the pin 28 inwardly so that w hen the collar'33 is rotated, the pin will be pushed between the lever 29 and the plate 23 to rock the said lever and force withdrawn from engagement with the lever 29 to allow the fabric guide spring'to with` draw the fabric-.guide from contact with the presser foot and increase the distance of the line of stitches from the edge of the fabric,-as shown in Fig. Ll.

36 represents a ribbon guide having one end adjustably mounted by means of a set screw 37 in the upper portion of the plate 23. This ribbon guide, forms the subject matter of an applicationiled January 2, 1912, Serial No. 669,082 of which this case is a division and detailed description and illustration herein will be unnecessary.

` The plate 23-is provided at its lower end with a lug 37. that yis adapted to enter into aknotch-38 in afhorizontal plate 39 secured to the plate 7 (see Fig. 6),. This notch has a beveled edge 40, with whichy the lug contacts as shown in Fig. 6. When the lug enters the notch the lower portion of they plate. 23 will be rocked on the stud 18 throwing the upper portion of said plate toward the presser foot and tilting the ribbon guide to its ribbon feeding position.

When it is desired to swing the ribbon guide Copies of this patentlmay be obtained for rsaid:

said lever rto actuate said pins and move to an inoperative position the lug 37 is withdrawn from the notch 38 and allowed to slide along the edge of the plate 39 into a slot 39', the sleeve 19 `sliding inwardly on the studj18 and' carrying the plate 23 with it and swinging the ribbon guide to an inoperative position.

I yclaim Aas my invention 1. The combination, with a stitching mechanismi4 anda presser foot, of a sliding fabricr guide, v,a'lslotted plate, a pin 'connected with said guide and projecting into said slot, a pin mountedk in said plate and engaging said first named pin,.a lever pivoted on said plate and. bearing on said second named pin, a spring normally tending to retract fabric guide and means for rocking said fabric guide toward said presserfoot. 2. The combination, with a* stitching against the pin 26, or

mechanism and a presser foot, of a spring Yretracted fabric guide, a stationary stud, a

rotatable collar mounted thereon, a lever, means actuated by the` movement of said lever for forcingsaid guide against the tension of said spring toward said presser foot, and a pin carried by said collar in position to engage and rock said lever.

y 3. The combination, with a machine frame,y of a stitching mechanism and a presser foot, a guideway provided in said frame, a spring retracted slide movable in said guideway, av `fabric guide carried by said slide, a rotatable member having'a finger grip and means operatively connecting said rotatable member with said slide for ward said presser foot against the tension of said spring.

5. The combination, with a stitching mechanism and a presser foot having acomparatively small, outwardly projecting pin thereon, of a fabric guide having a shank at n right angles substantially to saidv presser foot and adjustabletoward and from the same, and an end portion that is bent. parallel substantially with said ypresser foot and provided with a slot to receive 'the pin on said presser foot, a rotatable mechanism for forcing said guide toward said presser foot, and a spring device normally tending to retract said guide.

In witness whereof, I havehereunto set myhand this 16th day of vMay 1912.

FRANKLIN OHATFIELD.
